Now proceed to install client web ui on other machine:

here is the docker compose file:

services:
  nut:
    image: edgd1er/webnut
    container_name: webnut
    environment:
      - UPS_HOST=your-host.local.lan
      - UPS_PORT=3493
      - UPS_USER=admin
      - UPS_PASSWORD=secret
    restart: unless-stopped
    security_opt:
      - no-new-privileges:true
    networks:
      - nginxproxymanager_default
    ports:
      - 6543:6543
networks:
  nginxproxymanager_default:
    external: true
